Description:

FlatMol
a molecule drawing tool for the educator or student

Simple and flat, chemical structures made with this program are designed to be compatible with a paper surface rather than to compete with 3D models.

Tips:

Help Topics are accessible from the Menu
Undo is available (command Z) ["Edit" Menu]
Viewing styles may be changed ["View" Menu]
Molecules may be Rotated ["Edit" Menu]
Any atom may be drawn and then changed to an different element.

* Novice and Expert Modes
* Quickly fill all open valencies with Hydrogen atoms
* Quickly draw predefined three to six membered aliphatic rings plus benzene
* Fuse rings for the above ring types
* Remove an atom from a molecule (except from within rings)
* Number atoms sequentially
* See more features in the supporting web page.

Once complete, flatMol molecules may be saved for future editing, printed, saved as a .mol file (which can be read into 3D rendering programs), or saved as a pict. file.
Once saved as a pict. file, they may be dropped into a word processor or test program or converted (via other apps) to different formats if needed,

This program is designed to keep things simple; complicated ring structures or structures involving unusual bonds may not be able to be drawn here at all. I have chosen to disallow features such as unusual bonding or removal of random atoms within a ring group to keep other features ( such as rotation ) working properly.

* fewer keystrokes required for Atom and Bond changes

Simpler Help Window; “test canvas” removed

Rebuilt for Cocoa
Save Dialog now works properly

Bug fix : atom overlap no longer causes the application to freeze
(overlap is detected and not allowed)

If you had problems with prior versions, check the new one... - In response to another review, I drew up a bromobenzene, and it did not add extra hydrogens, so perhaps that was a bug that got fixed. As a chemist myself, I never add the extra hydrogens anyway because it's not essential for my particular work… but as long as it produces the diagram you want, that's good enough, right. Could the UI be better, of course (this is always true of everything), but most scientists are more concerned with spending their time making sure the guts of the program are working than whether or not the buttons are pretty. Having said that, I haven't found it any better or worse than any other chemical drawing program I've ever tried to use. I still find this program to be useful for all of the drawings I have needed to do. I definately recommend it to students of OChem for use in their reports. My advise is to bear in mind the limitations (stated in the description) and remember that you only paid about $5 for this; there is a reason that ChemDraw costs as much at it does.

Review by ScotLaRok

Absolute Piece of Crap. - I was looking for an alternative to the high-priced programs offered from Cambridge Soft (Bio Ultra Draw) and ChemDoodle so I clicked the download button and took my chances -- it's only $5 and Judy Long claimed in the description that the negative reviews were based on expectations that were not expressly documented in the description. So I rolled the dice. I have spent the past 4 hours constantly trying to make this program work. If you need to draw a simple molecule - then great…but if you need to draw any ring structure - good luck. Once you start creating multiple molecules (for example, trying to flip a pyridine and move it towards a ribose sugar), they begin to overlap and you are unable to select individual molecules and the program locks up - thus, requiring a "force quit". Of course none of the changes I made were carried through and I was forced to start with a prior save. If any of your molecule's boundaries even touch, then you run the risk of not being able to select them and the program doesn't know what to do so it gets stuck in an endless dialog prompt, from which you cannot get out unless you force quit. The adage of "you get what you pay for" is clearly illustrated here. Buyer Beware.
